Embodiment Construction

[0013] Combine below figure 1 , to further describe the embodiments of the present invention.

[0014] Such as figure 1 As shown, the collector consists of a double-layer transparent cover plate (1), a honeycomb structure (2), a heat absorbing plate coated with a solar selective coating (4), a metal container (5) encapsulated with a heat storage material, and a There are five parts of the casing (6) of thermal insulation material. The transparent cover plate and honeycomb material are polycarbonate or fiberglass, the heat absorbing plate is galvanized plate or aluminum plate, the heat storage material is low-temperature phase change material such as sodium sulfate decahydrate or paraffin, and the insulation material is polyurethane or polystyrene foam material . The honeycomb structure (2) is a rectangular tank body, located between the double-layer transparent cover plates (1), and functions to suppress heat convection. The heat absorbing plate (4) has a V-shaped structur...

Abstract

A solar heat collector containing heat accumulating material features that the heat accumulating material contained in a sealed metal container is arranged between the heat sucking plate and bottom plate of traditional flat-type air heat collector for sucking and accumulating the excessive solar heat.

Description

technical field [0001] The invention relates to a solar heat utilization device, in particular to a solar air heat collector combined with heat storage materials. It can be laid on the roof or placed in the yard, absorbing heat energy from solar radiation during the day, and using heat storage materials to continue releasing heat at night to achieve the purpose of heating the house or drying agricultural products. Background technique [0002] Flat-plate solar collectors are a major way to utilize solar energy, and are widely used in building heating, agricultural product drying and other fields. The existing solar flat-plate air heat collector is mainly composed of three parts: a transparent cover plate, a heat-absorbing plate, and an insulating shell. Although the flat plate collector has a large area to receive solar energy, it also has a large heat dissipation area. When the heat absorbing plate absorbs solar energy and heats up, the heat will flow from the upper cover...
